The research presented below examines the focus charting model in French nursing practice. Between the objectives targeted by this model and actual practice, where to place the reflective process of the nurse? To answer this question, the methodology used is the comprehensive approach. It is characterized by the production of semi-structured interviews of nurses using the model studied, but also by the in situ observation of practices. The results show that nurses engaged a reflexive process in the use of the focus charting model. This reflexive process is "in" the action rather than "on" or "for" the action. Nurse's position vis a vis at their disposal is investigated.
